SARPi on Pi2


I am having problems getting sarpi to work with a Raspberry Pi 2.

Downloaded this file
(http://sarpi.co.uk/files/rpi2/142/im...b18_sp1.img.xz)
and written it (using dd with the suggested command line switches of of=/dev/sde bs=65536) to a 16Gb micro SD card.

I have now done this with cards from Integral, Kingston and Digi-chip and they all report the same fault.

Every single one of them halts with seven green flashes of the LED.
According to the charts I can find this means there is no kernel.img present on the card.

When I inspect the fat32 partition created I can see a kernel.img (kernel7.img) file there.

So what file needs to be edited to make this boot system actually find this kernel7.img file?

The flashing green LED (7 times) means there's an error with the kernel.img (i.e. it cannot be found).

You could download kernel_sarpi2-4.14.18-armv7-1_slack14.2_10Feb18_sp1.txz and extract the kernel.img file and replace the one you have in your /boot directory.

You do not need to edit any file in order to get the system to find the kernel. This should all be handled by the RPi firmware. The RPi firmware is closed-source btw.

Thanks for the advice.

Will try downloading the kernel image and replacing the one on the SD card.

Shame that the firmware is closed as it would be nice to be able to hack about with that.

Thanks for the help.
That seemed to fix things.
Got it booting; all works as desired.
